The diploid number for the specie is 14 chromosomes. Diploid means the paired chromosomes as opposed to haploid which is 7 chromosomes.
G2 or gap 2 phase of the interphase is where DNA synthesis occurs and where the chromosomes are replicated to generate sister chromatids.
Answer:
It would be C
Explanation:
If you look at the tree you can see that one of the male's parents had the recessive allele, and one of the siblings has the ressive allele, the means the male could have the trait but isnt showing it.
Answer:
I = 62.5%
Explanation:
<u>Available data</u>:
- the wild-type DND1 gene confers resistance to attain viruses. Strains are susceptible to viruses
- The EDS1 gene confers resistance to powdery mildew, a type of fungal infection
- The genes are linked, eight map units apart on chromosome
- A third gene, IR 1. imparts resistance to certain lepidopteran leafminers and is 10 map units from EDS1 and 18 map units from DNDI
- The observed double crossover rate is 0.3%
According to this information, we can picture the position of each gene in the chromosome
---DND1----------------------EDS1-----------------------------------IR1---
║---------- 8MU---------║------------------10MU-------------║
║------------------------------18MU------------------------------║
The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
1% of recombinations = 1 map unit = 1cM. The maximum recombination frequency is always 50%.
So, if we know the distances between genes, we know their recombination percentages.
- DND1-EDS1 = 8 MU = 8% recombination
- EDSI-IR1 = 10 MU = 10% recombination
To calculate interference, first, we need to know the coefficient of coincidence, CC.
CC= observed double recombinant frequency/expected double recombinant frequency
<em>Note: </em>
- observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals
- expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.
CC= (0.003)/(0.08 x 0.1)
CC=0.003/0.008
CC=0.375
CC = 37.5%
The coefficient of interference, I, is complementary with CC.
I = 1 - CC
I = 1 - 0.375
I = 0.625
I = 62.5%
Answer:
63, grams
103, grams
Explanation:
According to the Academy of Nutrition and Dietetics endurance athletes, like Margaret needs about 0.55 to 0.9 grams of protein per pound while Strength-athletes that are trying to build muscle mass need more than 0.9 grams of protein per pound.
Since Margret is an Endurance athletic according to the question she will be needing:
115 lb x 0,55 =63,25 grams
115 lb x 0,9 =103,5 grams
Therefore Margaret should consume between 63 and 103 grams of protein daily.
Answer:
The triceps muscle extends when the biceps muscle is contracted.
Explanation:
The biceps and triceps muscles,work together in creating functional movement. These movements contribute to the ability to perform day to day tasks.
These muscles function in flexing and extending the arm. <em>Biceps for flexion</em> and<em> triceps for extension</em>. Both muscles work in an antagonistic fashion such that, the one doing the major motion is called the <em>primary mover</em> while the other muscle, is the <em>antagonist</em>. These muscles work in opposite direction, aiding the movement of the arm in both directions.
When biceps are contracted, the triceps are extended. Their antagonistic nature is beneficial because both muscles set the motion patterns at particular points. If we only had biceps extension of the elbow will be impossible and any movement that requires extension would not have been possible and vice versa.
